In addition, the consideration of constraints of physical or thermodynamic origin also introduces additional intriguing structures into chemical kinetics.
Motivated by the work of Horn and Jackson [1]}, who extended equilibrium states to complex balanced states, an algebro-geometric structure of chemical reaction systems was discovered and employed to study mass action systems in applied mathematics [2]}, [3]}, [4]}.
Other structures in chemical kinetics are also unveiled by using tools from graph theory, homological algebra, and others [5]}, [6]}, [7]}, [8]}, [9]}, [10]}, [11]}, [12]}.
